Standards.
-
IEEE Std 1070
Emergency restoration of transmission structures — Lindsey 1070-series ERS structures are designed and proof-tested to this standard.
-
Modular ERS
Lightweight, foundationless, guyed modular structures restore lines to 765 kV; configurable as dead-end, running-angle, tangent, herringbone, and chainette.
Categories Hawk sources from Lindsey Manufacturing.
Transmission & Distribution Products
Transmission and distribution hardware and insulator assemblies, modular Emergency Restoration System (ERS) structures, and TLM conductor monitors and SMARTLINE dynamic-line-rating sensors for grid monitoring.
View categoryStructural Hardware

Who owns Lindsey Manufacturing?
Lindsey Manufacturing (Lindsey Systems) is an independent, privately held U.S. manufacturer of transmission and distribution equipment, founded in 1947 and based in Azusa, California.
In April 2026, First Reserve completed a majority equity investment in Lindsey Systems. Lindsey continues to build its transmission hardware, ERS structures, and sensors under its own name.
What equipment does Hawk source from Lindsey Manufacturing?
Hawk sources Lindsey transmission and distribution hardware and insulator assemblies, Fail-Safe insulator bases, Emergency Restoration System (ERS) modular structures, and grid-monitoring sensors — TLM conductor monitors and the SMARTLINE dynamic-line-rating system.

What is the Lindsey Emergency Restoration System (ERS)?
The ERS is Lindsey's lightweight, modular, foundationless transmission-structure system for rapid line restoration after storm or fault damage. The guyed structures install in hours by hand, crane, or helicopter, and are reusable.
ERS components configure as dead-end, running-angle, tangent, herringbone, and chainette structures, and have restored lines at voltages up to 765 kV. The 1070-series ERS is designed and proof-tested to IEEE Std 1070.
What are Lindsey TLM and SMARTLINE?
The TLM is Lindsey's transmission-line conductor monitor — a sensor that supplies the live conductor data used for dynamic line rating.
SMARTLINE is Lindsey's dynamic-line-rating system, which uses TLM data to calculate real-time transmission-line capacity rather than relying on a fixed static rating.
What insulators and hardware does Lindsey make?
Lindsey makes EHV transmission hardware and insulator assemblies, pole-line hardware, and Fail-Safe insulator bases that yield predictably below the insulator's rated strength to hold the conductor above ground for repair.
Hardware is designed for bare-hand and hot-stick maintenance, and load-rated hardware is destructively tested by lot.
